PUMP
Pump control
Different pumps can be controlled depending on the sample changer ver-
sion. A rinsing and a aspiration pump can be installed on one changer
tower. These can be switched separately. The duration of rinsing and suc-
tion processes can be comfortably controlled with the line time of the
PUMP
command.
External pumps, e.g. for removing titration solutions containing solids, can
be controlled via remote output leads (remote socket, see
CTRL com-
mand).

Address
Pump address
1.rinse | 1.aspir | 2.rinse | 2.aspir
The address of a pump consists of the specification of
the changer tower (1 or 2) and the function of the pump
(rinsing=pump 1, aspirate=pump 2). It is valid for the
currently active changer.
State
Pump status
on | off
A pump can only be switched on or off. The pumping
duration can be controlled with the line time of the PUMP
command. Example:

Sample changer stirrer control
In contrast to the stirrer connections of the Titroprocessor
itself, the stirrer speed can be controlled on the 717 Sam-
ple changer.

The stirrer address always refers to the active changer.
With 1-tower changer models only 2 stirrers (722 Rod
stirrer or 741 Magnetic stirrer) can be connected.
